PC boots, and gets to safemode screen, but fails to start-up on any from list!
There have been NO hardware changes, only installation of VLC player a few days ago (because WMP was crashing).
ANy ideas, and what to do.....

Now sorted, tried memtest - no fault.
Then Ultimate Boot CD, and it detected bad sector in HDD which it repaired and I'm now surprised to be back up and running ;-))
BTW - yes my OS is in my sig, that's why I have it there, so I don't have to mention it, why can't people read!!

Thank You. In the future you can also state in your OP that we are discussing the computer in your sig in case members did not see this thread knowing that you would state the specs of a computer if it is not the one in your sig.
